<h4 class="subsection">3.19.48 Options for System V</h4>

<p>These additional options are available on System V Release 4 for
compatibility with other compilers on those systems:
</p>
<dl compact="compact">
<dd><a name="index-G-5"></a>
</dd>
<dt><code>-G</code></dt>
<dd><p>Create a shared object.
It is recommended that <samp>-symbolic</samp> or <samp>-shared</samp> be used instead.
</p>
<a name="index-Qy"></a>
</dd>
<dt><code>-Qy</code></dt>
<dd><p>Identify the versions of each tool used by the compiler, in a
<code>.ident</code> assembler directive in the output.
</p>
<a name="index-Qn"></a>
</dd>
<dt><code>-Qn</code></dt>
<dd><p>Refrain from adding <code>.ident</code> directives to the output file (this is
the default).
</p>
<a name="index-YP"></a>
</dd>
<dt><code>-YP,<var>dirs</var></code></dt>
<dd><p>Search the directories <var>dirs</var>, and no others, for libraries
specified with <samp>-l</samp>.
</p>
<a name="index-Ym"></a>
</dd>
<dt><code>-Ym,<var>dir</var></code></dt>
<dd><p>Look in the directory <var>dir</var> to find the M4 preprocessor.
The assembler uses this option.
</p></dd>
